I have a set of Mammoth Bars coming to me I won on Ebay. They are 3½" center, 6" riser, 31¾" wide, 11½" pullback. I didn't think about it until they were shipped, but I emailed the guy to see if they came with the mounting hardware. He said no. I then asked for the thread pitch required since, according to Dennis Kirk, there are 2 options. I have not received a response. Is there anybody here who has these or similar bars or just happens to know the answer?

 

Probably the same bolts holding your risers on now. I think they are 1/2" x 12 or 13 tpi

 

Yep! They are the same. ½" x 13. The bars look great.

I had to order a master cylinder though. And of course, since the master cylinder is going to be chrome, it was only proper to order the clutch lever, housings and switches in chrome as well.

Thanks for your help.
